Snails and Changes in Sea-Level

Nature volume 131, page 277 (1933)Cite this article

Abstract

IN NATURE of April 7, 1923, p. 464, I directed attention to the great changes in sea-level assumed by some geologists to have occurred during Pleistocene times. Reference was made to the small I. de Cima, close to Porto Santo, in the Madeira group. This islet has a very distinct species of snail, in great abundance, and if the postulated changes in sea-level actually occurred, it is hard to understand why the snail did not reach the main island, or, at another time, perhaps perish beneath the waves.
